The Hope R4+ LED Vision Standard UK Front Bike Light is small enough to use as a head torch, yet still gives out a massive 2000 lumens (1500 measured) for use on the most demanding rides. The R4+ features two power sequences, each with three light levels which allow users to maximise power or burntime. When the battery starts to run down and get low, you don't need to worry as this Hope light has a low battery warning mode giving you enough time to sort out a battery replacement or for you to get home before the unit completely shuts down.
